Specification of Letters Patent.

I Application filed March 22, 1920. Serial No. 367,670.

To all whom it may concern:

1n the county of Saline and State of,Mis

souri, have invented certain new and useful Improvements in Lubricators; and I do de-.

lare the following to be a full, clear, and exact description of theyinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reflngs, and to the letters andfigures of reference marked thereon, which'form a part of this specification. V

-This invention relates toa forced feed lubricating system for reciprocatory engines and theinvention contemplates the provision of means for introducing a lubricant at each alternate stroke of the plston, the lubricant preferably being fed into the "valve chest to be distributed over the movable parts, including the D-valve, the piston rings, etc., the invention bein particularly applicable in connectionwit locomotives although not necessarily limited thereto.

The figure in the drawings is view through a conventional form ofrecipwhich is a rocatory engine the valve chest,-the, D-valve Referring of reference: H

1 designates an which is a valve 4 which alternately become the inlet and exhaust ports for the cylinder 1, as'will be well understood. On the valve seat 5 is shown a conventional form of -D-valve 6 havin a valve stem 7 stem 8 of a engine cylinder, above may be prevented-from leaking.

Secured to the steam chest is a bracket member 10, carrying a pump cylinder 11, in piston 12 provided with a piston rod 13 projecting through a packing 14 and through the adjusting nut 15 on the endof the cylinder 11. The valve stem 7 and the piston rod 13. are connected by a cross head Y 16, as clearly shown.

The inlet to the pump communicates'with a pipe 17, having avcheck valve 18 therein opening in the direction of the arrow and said pipe is adapted to'be connected to. a

hydrostatic lubrication system on the loco a sectional or effecting the forced feed.- to the drawings numerals chest 2 having ports 3 and projecting through the threaded gland or packing, including an adjusting nut 9 whereby the steam, chest? .ters-Patent is:

which is connected motive, saidsystem constituting the source of lubricant supply to the pipe17, although I the inVentiOn is necessarily limitedto the inclusion of the particulartype of lubri cation system. ;The cylinder is also sc on nected to a pipe 19, communicating at 20 withthe valve chest of the engine and said pipe 19 is provided with a check valve 21,

open ng. "in the direction of the arrow or toward the steam chest. erence being had to the accompanying draw- The motion for the pump t be taken irectly ofl the valve stem 7 through the me diumof thecross-head 16 toywhich the rod 13is secured; therefore, when the" valve 6 1s moving in "one direction, for example,

time, being closed.-

pump; cylinder'll, the

1s reversin'git's move moving from'left'to right, the

piston'l2 will be moving during its ejecting;

stroke; that is, the lubricant which has been; v drawn into thecylinder 11 will, during this tlm'e be ejectedthrough pipe19, the valve 21 being open;

. Therefore, at each alternate stroke bf thelfi;

plston 22- and' consequently, at each alter,-

nate stroke of the valve 6 lubricant will be" ejected into the valve chest,

thereby keeping,

the parts constantly lubricated and by reducb- 4 ing therwear' and friction, ,reduce the cost of coal consumption in maintaining the en- "gine to the proper power standard.

It w ll be apparent from thefforegoing that the lubricating system may be readily installed-upQnexisting types of locomotives without. materially changing the construction-thereof, efi'ective in efliciently lubricating the valve cylinder rings out materially enhancing the cost of the en and that the invention will be and cooperating parts withgine and without effecting its construction ,What I claim and 1. In combination with the we chest a desire to secure by Let-,- n 1 a reciprocatory engine and a'hydrostatic lubrication 1 system,

cation system and the outlet to the valve chest of the engine, and meansmovable in of a 'pump,"thje inlet of I l to the hydrostatic lubriresponse to movement of the valve-in the"- valve chest for operating said pump; toaloternately draw in lubricant from the hydrostatic lubrication system and expel it into the valve chest.

2. The combination With the valve chest 5 of a reciprocatory piston engine of a cylin-- der above the valve chest having a hydrostatic lubricator inlet and an outlet 'com-- municating with the valve chest, and a charge-measuring piston in the cylinder and moving in synchronism with the valve in the 10 valve chest.

In testimony whereof I aflix my signature.
